Hvo_1477 is required for growth on DNA. (A) Deletion of chromosomal gene Hvo_1477 in H. volcanii strain H26. PCR amplification of H26 and Δ Hvo_1477 template DNA using the forward primer for the upstream Hvo_1477 flanking region, and the reverse primer of the downstream flanking region (Hvo_1477FR1_F and Hvo_1477FR2_R, Table 3). (B) Growth with eDNA in CN media for H26 (parental strain, black filled squares), Δ Hvo_1477 (red filled triangles) and Δ Hvo_1477 with pKD409_1477c complementation plasmid (Δ Hvo_1477c, purple circles). OD was measured every 3 h within a shaking and incubated 96-well plate reader. (C) Increase in optical density 96 h after supplementation with KH2PO4, DNA solvent (continued starvation), or eDNA. Error bars represent standard deviation of triplicate cultures.
